SMP 8.1 RU6

SMP = Symantec Management Platform

Fusion registry entry pointing to the Assembly publishing policy is missing.
Why the .NET Framework managed registry entry is missing is unknown.

To find the missing registry entry perform the following.

1. Download and start Process Monitor.
2. Restart IIS (Admin Command Line > iisreset) and reload the Management Console to reproduce the error.
   1. The iisreset forces the assemblies to be reloaded.
3. Stop and save the Process Monitor trace.
4. Filter the process Monitor trace for "policy.7.1.Altiris.Reporting.Parameters" or similar strings.
5. These steps may need to be repeated to rebuild the full registry entry step-by-step.

Recreate the registry entry for the Assembly Publishing policy.
Below is an example only (not valid for all environments):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion\PublisherPolicy\Default\v4.0_policy.7.1.Altiris.Reporting.Parameters__d516cb311cfb6e4f\1\8.1.4528.0\200
